PHP has some handy Date classes, including one for specifying date intervals. But you need to be wary of some idiosyncrasies, as I just found out.

January 1, 2017TIL that you need to give Gravity Forms add-ons some capabilities, otherwise they might disappear from the WordPress admin.
exim4 with wildcard email aliases
December 31, 2016When you configure exim4 as your email transport, you will likely need to tell it to replace some user names with aliases. To make your life simpler, use wildcards to do the job for you.

December 23, 2016Sometimes the WooCommerce out of stock message isn’t quite appropriate. Here’s a couple of ways to change that message.
Searching custom meta on custom post types
